UNITED STATES 2,096,714 BEER con. CLEANER `David Haldane, Chicago, lIll., assigno'r to Brass Products Company, Chicago, Ill.,a vc o-partnefrship composed of Harry W. Anderson and *Her-y man W. Kuehl Application Apri1'7729, 1935, Serial No.118,7:56 s Claims'. (c1. 22e- 12) An object of this invention is to provide a simplified and condensed form of beer coil cleaner, and one which is adapted particularly for use on a water pressure system.

Another object is to provide in a cleaner of this type means for readily separating the pearls or small solid particles as glass beads from the sponges or larger compressible cleaning units, such as sponge rubber.

These and other objects, as will hereinafter appear, are accomplished by this invention which is fully described in the following specification and shown in the accompanying drawings in Which- Figure 1 is a front elevation of the device partly in section, showing it attached to a beer coil or the like to be cleaned;

Fig. 2 is a partial vertical section on the line 2-2 of Fig. 1;

Fig. 3 is a horizontal section on the line 3-3 of Fig. 2;

Fig. 4 is a partial enlarged vertical section on the line 4-4 of Fig. 3;

Fig. 5 is a section through the plug valve on the line 5 of Fig. 4; and

Fig. 6 is a partial enlarged section on the line 6 of Fig. 1.

The embodiment illustrated comprises a base I0 to which is secured a tting II which has a 30 screw threaded nozzle I2 at one end adapted to be connected by means of a hose or the like not shown, but which may be carried to a drain. A pipe I3 connects into the top of the fitting I I, and

this is screwed into the bottom of a valve casting Y I4 into which is rotatably tted a plug valve I5 which is operated by means of a handle I6.

The casting I4 has four passages for water,

namely, a passage I 'I leading to the pipe I3, anV

inlet water passage I8 adapted to be connected with a Water faucet or other source of water supply under pressure, and two lateral passages I9, 20 (Fig. 1) which have flaring lower ends I9a,

2l)a respectively, which form the upper ends of the chambers 2|, 22.

'Ihe plug valve I5 is conical and is pressed against a conical seat in any well known manner. This valve has two lateral grooves |53, I5b which are preferably semi-cylindrical. A passage I5c leads from the groove I5a to the end of the groove where it communicates with the passage I8 of Fig. 2. The chamberZI is provided with a cylindrical glass side wall 23 which is provided with a threaded bottom 24. A sleeve 25 has ends into which screw the threaded bottom 24 and the aan@ an@ threaded end |95. an@ has lateral windows 26. Within the sleeve are a glass cylinder 23- and aring 21 withsuitable gaskets placed between these parts and the end I92L to prevent leakage of Water passing therethrough.

A relatively fine mesh screen 28 is provided at the top of the chamber, While a coarse mesh screen 29 is carried in a circular frame 30 which is mounted on a shaft V3| which passes through the side of the chamber and is rotatable by means of a handle 32. The screen 29 is suiciently ne to stop sponges 33 and hold them, say in the chamber 2|, but coarse enough to permit the passage of pearls 34, as shown in the lower portion of the chamber 22. I'he screen 28, however, is ne enough `to prevent the passage of the pearls. A valve 35 is provided beneath one of the chambers to retain the pearls therein when the valve is shut olf, as shown inV Fig. 1. The lower ends of the chambersV are connected through suitable connections with the pipes and coils 36 to be cleaned. These are shown diagrammatically in Fig. 1.

The operation of the device is as follows: Starting with the Sponges in the chamber 2l and the pearls in the chamber 22, the valve I5 is turned so as to force water through the chamber 22, the valve 35 then being opened so as to permit the water and the pearls to pass down from right to left through the coil 36, and up into the chamber 2I where the pearls are stopped by the screen 28, but the water passes on through the pipe I3 to the drain.

Upon turning the valve I5 so as to reverse the direction of ow through the chambers 2|, 22 Y ber 22, again being stopped bythene mesh screen at the top of the latter chamber. Thus by reversing the valve I5 the pearls can be sent back and forth throughthe coil 36 as often as may be deemed necessary to clean the coil of'any deposit which may have formed therein.V Y

To iinish this cleaning, the screens 29 at the bottom two chambers are then turned so as to permit the Sponges 33 to pass through the coils with the pearls as the direction of flow of the water is reversed by means of the valve I5.v Tolend up the operation, the sponges 33 may be left in either chamber desired by turning the screen inv the bottom of the chamber so as to retain them after they are in that chamber. The pearlsl must end up in the chamber 22, after which the valve 35 isY turned so as to retain them. Any water that is left in these chambers may be drained out by turning the apparatus upside Ydown after detachment from the coil 36 and from the faucet and from the drain pipes.

While I have shown and described but a single embodiment of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made which do not depart from the spirit and scope of the invention as disclosed in the appended claims.

1. In a device of the class described, two chambers each having an upper and a lower orice, relatively ne mesh screen across the upper end of the chamber, inlet and outlet water passages, a rotatable valve adapted to selectively operatively connect the upper orice of one of the chambers to either the inlet or the outlet passage and the other orifice to the other passage, a relatively coarse mesh screen in each of the lower orices, said coarse mesh screen being adapted to pass pearls but not Sponges, means for shifting each coarse mesh screen from open position in which it passes both pearls and sponges to closed position so as to prevent the passage of sponges but permitting the passage of pearls, and a valve in one of the lower orices for substantially closing sarne to prevent the passage of pearls.

2. In a device of the class described, two chambers each having an upper and a lower orice, relatively fine mesh screens across the upper ends of the chambers, inlet and outlet water passages, a rotatable valve adapted to selectively operatively connect the upper orifice of one of the chambers to either the inlet or the outlet passage and the other orifice to the other passage, a relatively coarse mesh screen in each of the lower orices, said coarse mesh screen being adapted to permit the passage of pearls but not sponges, and means for shifting each coarse mesh screen to or from the position in which it acts as a barrier to the passage of the Sponges.

3. A device as set forth in claim 2, having a valve in one of the lower orifices for substantially closing the same to prevent the passage of pearls.
